When an external force deforms a solid, internal restoring forces are developed in the body giving rise to stress and strain. Draw the stress-strain diagram and mark the positions of elastic limit and the regions of elastic and plastic behaviors.

When an external force deforms a solid, internal restoring forces are developed in the body giving rise to stress and strain. Define stress and strain.

Draw the stress-strain graph of a loading wire. Mark the following points : i) Elastic limit ii) Fracture point iii) Plastic region iv) Elastic region

Elasticity is the property of a body by which it regains its original state on the removal of the deforming force. The figure given below shows the stress-strain curve for a given material. What are the Youngs modulus and approximate yield strength for this material?
